This is the guy I've been talking about for a couple of years, and who I would want:
I'll start with a Rozier package and build on from there.
I like Vucevic as well, but his asking price is probably quite high right now. Although it's probably in Orlando's best interest to make a choice between making a trade for an All Star PG or trading away Vucevic for draft picks.
Another problem is that it's very hard to match salaries.
And he is a rental (UFA in 2019). He would be a nice fit on the team but we would have to trade maybe Marcus Smart in order for salaries to match. I don't like him that much.
He makes 12.75 this year which isn't too bad. If Morris or Baynes is traded, it isn't that difficult to come up with a trade that works. It is just about whether you would want to part with Morris or Baynes to acquire him (Baynes can be moved next weekend). Baynes/Morris, Rozier and Yabu works financially and that seems like a fairly reasonable trade for both teams (I'd rather keep Morris so I'd propose Baynes). The trade does increase the tax for Boston, making it far more difficult to get out of it at some point, but I think that might be worth it for Boston as Vucevic fills a definite need. Orlando gets a younger PG prospect and can take a flyer on Yabu, while letting Baynes play some of Vucevic's role. Boston upgrades its center spot.
So post trade Boston's rotation would be Irving, Smart, Brown, Tatum, Hayward, Morris, Horford, and Vucevic. That is a pretty darn good top 8. Some depth is lost, but if that team enters the playoffs healthy I'd feel pretty darn good about it coming out of the East and giving the Warriors a real run for their money in the finals.
